A Fast scanning X-ray CT system was developed to visualize dynamic motion of interface in multi-phase flow. The scanning time less than 4msec. was achieve by using 18 pulsed X-ray generators and highly sensitive 256-pixel CdTe line sensor modules. The sensor device technology is based on their prototypes previously assembled for high-resolution radiography and tomography imaging of electronic parts. Equipped with the above CdTe modules, the fast X-ray CT system was able to visualize the 50mm diameter cross section with a spatial resolution of 2.8mm. When the system was applied to an air-water two-phase flow and a simplified fluidized bed system, it successfully quantified the multi-dimensional characteristics of interface in flow.
